To all whom it may concern: 1

Be it known that I, CHARLES W. CALL, J r.,

a citizen of the United States, residing at Northport, in the county of Suffolk and State of New York, have invented new and useful Improvements in Marine Craft, of

which the following is a specification.

This invention relates to marine craft of the high speed type, the main object of the invention being to provide aboat or vesselhaving sustaining planes adapted to, glide through the water at or near the surface thereof when the vessel is in motion, thereby diminishing the resistance to propulsion and enabling higher speeds to be obtained than is possible with vessels having large displacement and whose hulls are forced bodily by power through the water.

A further object of the invention is to provide a vessel of this character in which the hydroplanes or flotation surfaces are so arranged as to secure stability and safety without the necessity of employing a heavy or cumbersome onstruction, thereby enabling the weight of the vessel to be reduced to the minimum to diminish'both the water and air resistance to its motion to a material extent. I

A still further object of'the invention is to provide a boat of this character having leveling planes for cooperation with the hydroplanes', whereby the depth of submergence of the latter may be controlled as circumstances may require. in the operation of the vessel to control the speed and secure safety of the vessel under varying conditions. v

A still further object of the invention is to provide a vessel of the character described in which the propeller is adjustable to regulate its depth of submergence to secure max.

imum efliciency under the difierent contingencies of service.

The invention consists of thefeatures of construction, combination and arrangement of parts, hereinafter fully described andclaimed, reference being had to theaccompanying drawings, in which I Figure 1 is a view in side elevation of a form of vesselembodying my inventionhav ing a hull or body which serves as the flota tion medium when the vessel is at rest, afl

ortion of the adjacent side wall of, said iiull or body being broken away. Fig. 2 is a top plan view of the vesselshown in Fig.-1. Fig. 3 is a rear end elevation of thesame.

' Fig. Lis-a'side elevation similar to Fig. 1

of a catamaran type of vessel embodying my invention. Fig. 5 1s a top plan view of the vessel shown in Fig. 4. Fig.6 is a rear end elevation of the same.

Referring to Figs. 1 to 3, inclusive, of the drawings,1 designates the body or hull of the vessel, which may be in the form of a barge or. scow, to the underside of which are bolted or otherwise secured parallel, depending longitudinal frames 2 and 3, disposed on opposite sides of the longitudinal center of said body or hull. Each of these frames comprises a horizontal platform or superstructure 4 from which depend inner and outer series of supporting rods 5 and 6 connected at their lower ends by cross pieces 7,, the rods of each series, being further connected in pairs by crossed stays -8, of wire or other suitable material, thus securing strength and rigidity of construction.

Secured to the lower ends of the supporting rods of each frame 2 and 3 are hydroplanes 9 and 10 which extend longitudinally in parallel relation and horizontally or in parallel relation with the bottom or deck portion of the body 1. These hydroplanes constitute the flotation surfaces and may be formed of wood, metal or othersuitable material, and made of any shape suit-able for the purpose. The dotted line A-A indicates the water linegvhen the vessel is at rest, and the dotted line BB the water line when the vessel is in motion, from which it will be seen that the planes 9 and 10 the body of water adjacent the surface. The water will thus flow in effect along the upper and lower surfaces of the planes, which will have a gliding motion therethrough, whereby the sustainingpressure of the water will be secured to insure adequate stability of the vessel, while at the same time the planes will pass through the water without material resistance, enabling high speed'to be obtained at the expenditure of comparatively low driving power For the purpose of regulating the depth of submergence of'the hydroplanes, I provide each hydroplane with a fore and an aft lifting plane 11 and 12, respectively, said lifting planes bein pivoted for vertical movement at their orward ends, as at 13, to the underside of the hydroplanes and pivoted at their rear or free endsto okes 14 on the lower ends of adjusting re s 15. The

'Will be submerged so as to travel through rods 15 extend upwardly through and areslidably mounted in suitable openings in the hydroplane and deck. orbottom wall-of the hull and have rack toothed upper ends 16,.

the rack toothed ends of the respective sets 'of fore andaft adjustingrods meshing with pinionsz l7 upon front and rear transverse shafts. 18 and 19. To these shafts" are connected the free ends of pairs of cables 20 and 21 which are wound at their opposite or inner ends in reverse directions; around a drum 22 the shaft of which carries a leverv 23 by which the drum may be turned to simultaneously rot-ate the shafts 18 and 19 inwardly to raise the adjusting rods or to simultaneously rotate said shafts outwardly to depress the rods.

i made in sections or otherwise constructed so The lifting planes are adapted. when de-- pressed to assume an angular position with respect to the hydroplanes, said'lifting planes inclining downwardly and rearwardly so as to regulate the depth of submergence of the hydroplaneslthrough'the tendency of'said lifting planes to ride 11 wardly in the body of water. Through te the liftingplanes from a normal elevated position or an upward adjustment of-said planes from-their limit of downward movement the vessel as a whole may be raised or lowered when the vessel is in mot-ion, thus enabling the resistance of the planes to pro- .pulsion' to be varied and the level of travel ofthe planes to beregulated according to the depth and density of the body 'of water through which they travel.

as to be operated by the mechanism described to simultaneously raise or lower the liftingv planes,

ort and starboard liftsel in rounding a steering of the same in ward portion of the deck and which is arranged in a suitably inclined position. To the shaft 29 of this motor is connected, by a universal joint 30, the upper end of a downwardly and rearwardly inclined propeller shaft 31 carrying at its lower end a screw propeller 32 arranged on a line between and. slightly above the rear ends of the two hydrop1anes.- This shaft is jourby their angle of inclination downward adjustment of j while at the same time per in ependentlyadjusted by( auxiliary operating devices to-tilt the ves turn and to facilitate theperforming various evolutions in the water. vAt the rear of the vessel and in the central line thereof is ar-' ranged a rudder 24 carried'by a'steeringpost 25 hinged or pivoted on a rod26 se-a cured at its upper end to the platform 4 and; atits lower end to a cross pieceor brace; 27. Any suitable means may be employed' for turning this post to adjust the rudder.;

The propelling mechanism employed com-.1 prises a motor 28 mounted upon the for-' na led adjacent its lower end in a bearing 33 carried by a cross rod 34; provided on its outer extremities with sleeves slidably engaging guide rods -fixed at their "upper ends to the deck and at their lower ends to the two hydroplanes. This construction allows the lower end of the shaft to be raised or lowered to vary the working level of the propeller as circumstances may require, the sleeves of the rod 34 beingprovided with set screws or clamping members 37 to. secure the rod in adjusted position. A seat 38 maybe provided upon the deck at a suitable point in proximity to the motor and steering gear, so that the pilot or driver may ,conveniently control and operate the same.

In the form of my invention disclosed in Figs. 4 to 6, inclusive, the same general construction and arrangement of frame secf tions, hydroplanes, lifting planes, adjusting devices for the lifting planes and propelling mechanism is employed, the vessel therein shown, however, being provided with a pair of spaced parallel pontoons or floats 39 arranged between the hull or bodyand the plane carrying frames, said pontoons or oats being bolted or otherwise secured to the body and carrying frames and connected and reinforced by transversebrace bars 40 and crossedstays 41. With this construe tion it will be understood that the pontoons or floats increase the fiotation surface and buoy the vessel to a great degree when "at rest or traveling slowly through'the water,

a catamaran type of body or hull thus being j provided. As either form of body disclosed If desired, the shafts 18 and 19' may be may be employed, or any other "suitable form, I do not limit myself in this particular.

-It will be apparent from the foregoing description that in starting theivesselin mo tion the lifting planes may be gradually depressed as the speed of the vessel increases to lift the vessel until .the hydroplanes serve as the sole sustaining medium and are raised to the desired distance below the surface of the water, whereby the water resistance will be gradually decreased, allowing the vessel board may be reduced to aslarge a degree as possible consistent with safety, so as to decrease the air resistance and furtherincrease the speed capacity of the vessel.
